Rector, &C., of Christ Church, Phila. v. Cty. of Phila.

Mr. Justice CAMPBELL delivered the opinion of the court This cause comes before this court upon a writ of error to the. Supreme Court of Pennsylvánia, under the 25th section of the act of Congress, of th"9'24th September, 1789.' In the year 1833 the Legislature of Pennsylvania passed an act which recited “ that Christ Church Hospital, in the city of Philadelphia, had for many years afforded an asylum to numerous poor and _distressed widowsj who would probably else have become a public charge; and it being represented that in consequence of the decay of the buildings of the hospital estate, and the increasing burden of taxes, its means are curtailed, and its usefulness limited,” they enacted, “that the real property, including ground rents, now belonging and.payable to Christ Church .Hospital, in the city of Philadelphia, so long as the. same shall continuN to belong- to the said hospital ah'*11’ be and remain free from taxes.” In the year 1851 the same authority -enacted “ that all property; real and personal, belonging to ány association or ineor *302 porated company which is now by-law exempt from taxation, other than that which is in the actual use and occupation of such association or incorporated company, and from which an income or revenue is derived-by the owners thereof, shall hereafter be subject to taxation in the' same manner, and for the same purposes as other property is now by law taxable,-and so much of any law as is hereby altered and supplied be and the same is hereby repealed.” It was decided in the Supreme Court of Pennsylvania, that the exemption conferred upon these plaintiffs by the act of '1833 was partially repealed by the act of 1851, and that an assessment of á portion of their real property under the act of 1851 was- not repugnant to the Constitution of the United States, as tending to impair a legislative contract they, alleged to be contained in the act of As sem.bly of 1833 aforesaid. ■ The plaintiffs claim that the exemption conceded by the act of 1833 is perpetual, and that the act itself' is i'n effect a contract. This ■ concession of the Legislature was spontaneous, and no service or duty, or other remunerative condition,, was imposed on the corporation. It belongs to the class of laws denominated privilegia favofabilia. It. attached only to. such real property as belonged to the corporation, and While it remained as its property; but it is nota necessary implication from these facts that the concession is perpetual, or was designed to continue during the corporate existence. Such an interpretation is not to be favored, as the power of taxation is necessary to the existence of the State, and must be exerted according to the varyiug conditions of the Commonwealth. The act of,1833 belongs to a class of statutes-in which the narrowest meaning is to be taken which will fairly carry .out the intent of the Legislature, All laws, all-political institutions, are dispositions for the future, and their professed object is. to afford a steady and permanent security to the .interests of society. Bentham says, “that all laws may be said to be framed with a view to'-perpetuity; but perpetual es not synonymous to irrevocable; and the principle on which all laws ought to bo, and the greater part of them have been established, is that of defeasible perpetuity — a perpetuity defeasi *303 ble by an alteration of tbe circumstances and r'easons on which the law is founded.” The inducements tEat moved the Legislature to concede the favor contained in the act of 1833 are special, and were probably temporary in their operation. The usefulness of the corporation had been curtailed in consequence of the decay of their buildings and the burden, of taxes. It may be supposed that in eighteen years the buildings would be renovated, a,nd that the corporation would be able afterwards to sustain some share of the taxation of the State. The act of 1851 embodies the sense of the Legislature to this effect. It is in the nature of such a privilege as the act of 1833 confers, that irt exists bene placitum, and may be revoked at the pleasure of the sovereign. Such was the conclusion of the courts in Commonwealth v . Bird, 12 Mass., 442; Dale v. Governor, 3 Stew., 387; Alexander v. Willington, 2 Russ. and M., 35; 12 Harris, 232; Lindley’s Jurisp., sec. 42. It is -the opinion of the court that there is no error in the judgment of the Supreme Court, within the scope of the writ to that court, and its judgment is affirmed- -
